QM/MM electrostatic embedding calculations with Gaussian. Unlike most other QM programs, Gaussian calculations with point charges include a contribution from point charge/point charge electrostatic interactions. In ChemShell these terms are calculated by the MM theory and so they must be subtracted from the Gaussian result to avoid double counting.

QM/MM和Gaussian的ONIOM有联系，又有区别。 1、传统的QM/MM必须是一部分使用量子化学方法（QM），另一部分使用分子力学方法（MM），但是对于Gaussian的ONIOM方法，在不考虑计算资源承受能力的情况下，可以对任何一部分使用任何一种Gaussian软件支持的方法。

First, the energy of the total system, con-sisting of both QM and MM regions, is evaluated at the MM level. The QM energy of the isolated QM subsystem is added in the second step. Third, the MM energy of the QM subsystem is com-puted and subtracted. Show charged molecules. molUP quickly identifies the positive and negatively charged molecules in the system (blue and red surfaces) After the assigning of ONIOM layers, this interface can also be used to estimate the charge of each layer (required for any QM/MM calculation).
